-# fai_chain_studio — Ch∆In Studio (Flutter GUI)
-
-Die grafische Oberfläche der Ch∆In-Plattform (Studio). Gehört dem `chain`-Agenten
-(siehe `../../shared/AGENTS.md`). Plattform-/Naming-Konventionen und die
-Zero-Learning-Curve-Regeln stammen aus dem Haupt-Repo `fai_chain` (dort `CLAUDE.md`).
-
-## Design
-Basis: `../../shared/DESIGN.md`. Studio-Abweichung: Zero-Learning-Curve führend
-(Klartext, Inline-Hilfe, kopierbare Fehler); **Akzent bleibt Blau** (Wiedererkennung der
-bestehenden Studio-Identität), nicht Petrol. Dark + Light sind Release-Gate.
-
-## UI-Verifikations-Gate (PFLICHT)
-Keine „fertig"-Meldung zu UI-Arbeit ohne:
-1. **Frischen eigenen Screenshot-Beleg** der geänderten Screens — **hell UND dunkel**
-   (wie in `fai_chain` gefordert). Nicht aus dem Gedächtnis, nicht „sollte so aussehen".
-2. **Durchgespielten Klick-Flow:** die betroffene Interaktion real im laufenden Studio
-   klicken/bedienen — nicht nur statisch gerendert prüfen. Sonst wiederkehrendes Muster:
-   „fertig gemeldet, aber der Klick tut nichts".
-3. Bewertung gegen `shared/DESIGN.md` + die Studio-Abweichung oben; Fehlermeldungen
-   kopierbar; Theme-Umschaltung schaltet wirklich alles um.
-
-Testzustände danach zurücksetzen. Stefan nutzt meist Safari — Web-Ansichten dort mitdenken.
